So I have purchased an investment house has that has an older smaller pool (21x12) with only a 5 foot deep end. The pool company refers to it as a small L. The house has been sitting for over 2 years, the liner is leaky and has gone hard and crusty so its getting a new liner, Motor is dead, and was also rigged up improperly using a 120V plug and extension cord. It also has had most of its extras striped away such as the booster pump and pool cleaner as well as its salt system, heater and small fountain. Im wanting to put the entire pool back together with all new equipment. But when I'm going to order new equipment I'm met with an abundance of choices and prices for things. Can you oversize in a bad way on pools? For instance a 115k btu heater is 1600, but a 400k btu heater is only 300 more. So I'm inclined to go with the larger heater, same goes for the DE filter, I'm sure a small filter would work but a 60 or 72 sqft filter is only a couple hundred bucks more. Again can I go too large on these? IM also planning on doing an intelliflo variable speed, The pool builder professes to think that a 1hp pump is more than enough for everything including the fountain, but being that the intelliflo is variable speed won't the increase in size really not matter since you can just turn it down? Would appreciate any help or suggestions.
Its a strange pool as far as layout. There is one dedicated return line not hooked up to the pump that I'm guessing is for the auto cleaner the pump hook up seems to T off the return like for suction then hook up to the booster pump and then that water is sent to its own pipe. Im not sure if its ok or not for it to suck water from the 2" return line for a water source but the pool builder says it should be fine. I thought this was for the fountain but the fountain has its own valve off the main circulation pump. Also there are two jets in the steps that you can open a valve that lets them suck in air that makes a lot of bubbles. Then instead of a main drain there is a return line at the bottom of the pool, then one final wall return in the wider part of the pool (the L). It has two skimmers for suction, but no independent control at the pump, theres just one line leading to them. It seems like a botched together pool really. I have never seen a floor return in leau of a main drain. But some people think pressure is better than suction and I guess this will help heat the pool better since the fresh hot water enters at the deepest part of the pool. Thanks all for the input!
Heres the equipment the pool builder and I are sort of thinking about, but am open to suggestions.
Pentair Intelliflo Variable speed pump. (400 dollar for upgrade to SVRS system)
Pentair sta-rite 60 sqft DE filter (150 dollars for upgrade to 72sqft model)
Sta-rite max-e-therm 400k BTU heater (gas line hook up not included)

Here is the pool as it sits now, not very big and not very glamorous.
